Fike’s ValveGuard™ rupture disks are designed to reduce maintenance procedures, increase operating potential and save money. ValveGuards are rupture discs that isolate pressure relief valves, protecting them from process media and downstream contaminants. They are effective for both vapour and liquid applications. ValveGuards aim to prevent pressure reliefvalves from suffering from corrosion, build-up, polymerization, fouling or simmering.
